第三种

嗯是这样的 我之前也是做的分段控件 其实是有效果的 但是点击很不明显，后来是用了4张图片，2张是作为高亮图片。
UIImage *segment_hightImage2 = [UIImage p_w_picpathNamed:NAME_SEGMENTINDEXSECOND_HIGHLIGHTIMAGE];

[m_catalogControl setImage:segment_hightImage2 forSegmentAtIndex:1];

UIImage *segment_p_w_picpath4 = [UIImage p_w_picpathNamed:NAME_SEGMENTINDEXFIRST_IMAGE];//此处设置了分段控件选中第二个item的高亮图片

[m_catalogControl setImage:segment_p_w_picpath4 forSegmentAtIndex:0];

注意交错就可以了 点击2位置的时候把其他的再设置为默认图片，被点的设置为高亮图片
